Application filed llpril 19. 1906. Serial No- 312.676-

vide a take-up roll for the controlling sheet l of an automatic musical instrument which i shall be adapted to serve that purpose for sheetsof the severaldifierent widths which are commonly employed,to Wit, for 58 notes, notes and 88 notes,'respectively.

The invention consists in the features of construction set out in the claims.

In the drawings :Figure l is a side elevation of a take-up roll embodying this inj vention. Fig. 2 is'a partly sectionalside/ elevation, section being made axially at portions of the length. Fig. 3 is a section at the line on Fig. Figs. 4 and 5 are elevations of the driving and centering escutchcon plates, respectively.

A is a shaft of the roll. It is provided at one end with suitable means for driving en gagement and at the other end with suitable means for centering it. These means may be in any of the customary forms.

Upon the shaft, .ocoupying the middle portion of its length, there is a short section of roll, B, which is made fast to the shaft in any convenient manner and is preferably integral therewith, and has the customary. button, b, for attachingthe end of the controlling sheet.

Mounted upon the shaft at opposite sidesof the middle portion, B, there are end sections, C, C, of the roll. Upon the outer end of each of the sections, C, there is secured a flange, D. The mode in which it is thus secured will be hereinafterdescribed. The two end sections, 0, C, with their respective. flanges, D, are adapted to be adjusted longitudinally on the shaft, A, and set at different distances from the middle portion, l). When they are set at'the extreme outer positions, the distance between their fianges is designed to be such as to accommodate the SS-note controlling sheet. For holding. them at this position, there is lodged in a longitudinal groove, 0, in each end seotion,.-C, a; spring catch, F, secured at one-end to the struments {roll section and adapted at the other end three notches, a, a and which is. producedto engage one of the a formed in a rib, on the shaft, A, preferably by a piece of wire bent at the ends for engaging the shaft as shown in Fig. 2

two'iianges areen aged in the notches, a, the flanges are spaced longitudinally of the roll for an 88-note sheet. The roll sections, C, C, may be moved longitudinally toward each other by applying moderate pressure, and the catches being engaged with the notches, a, the flanges are spaced for a 65-note sheet. Being similarly moved still farther inward toward the middle section, B, the catches become engaged with the notches, (1, and thereby the flanges are held suitably spaced apart for a 58-note sheet. The ribs,- A engaging the sarne longitudinal groove, c, of

therespective endsections, C, prevent the latter from turning on the shaft. The means for driving en agement of the roll is preferably a mere en plate or escut'cheon, K, having a s uare hole, 7c, and the means for centering t e'opposite end is a similar escutchebn, K, having around hole, 16. These escutcheon plates being each slightly greater in diameter than the rollshaft, and, therefore, than the center opening. in the movable section and in the flange plates, serve to prevent the section, (j, from coming off the shaft, said escutcheon, plates bein applied and screwed to the end of the shaft by screws, 1, after the sections, 0, C, are placed thereon.

. When the catches of the date themselves slightly to the ex' ansion .Oursthrough changes of moisture and temperature in the atmosphere, they are each attached to the roll sections by means of three screws, H, H, H, on which it is guided-and under. whose heads around the screws are lodged coil springs, J, which yield and permit the flanges to fo low the expansion and contraction of .the paper.

1. Atake-up roll for automatic musical incomprising a shaft two roll sections mounted thereon having flanges at their outer ends, the shaft having notches at ositions in opposite directions from the middle point of-its length and disenga eable catches mounted in the respective roll sections for engaging the notches.
